Abstract

The dielectric response dispersion in the solid solution 0.9Pb0.95Sr0.05(Zr0.52Ti0.48)O3–0.05Pb(Zn1/3Nb2/3)O3–0.05Pb(Mn1/3Sb2/3)O3 + 0.1 mol % CeO in the vicinity of a diffuse ferroelectric phase transition was studied within the temperature range of 20–500°C at frequencies of 25 Hz–100 kHz. Observed dielectric relaxation process is characterized by features inherent in both conventional and relaxor ferroelectrics. It was shown that the temperature dependence of the relaxation time can be satisfactorily described by the Arrhenius law with a temperature-dependent activation energy.
